To ZZ whom t may concerns A Be 1t known that I, LUTHER L. ia'rns, a

i citizen of the United States, residing` at San Cars, of which the following is a specification. l

This invention relates to improvements in railway cars and more particularly to rrefrigerator cars.

Cars of this general type are usuallyprovided 'with hatches adjacent to each endv and it is the object of this invention to apply the insulation for the top ofthe car in one continuous sheet, from side to -side and The insulation extending continuously from endto end andcontinuously from side to side of the car as applied'in accordancev with the invention not only simplifies the construction of the car,but also adds to its efficiency as a refrigerator unit.

While the preferred form of this invention is illustrated upon the accompanyingsheets kof drawings, yet it is to be understood y vthat minor detail changes may be made without departing fromA the scope thereof.

Figure l is a top plan view ofa portiony of a car of this type with the roof removed illustrating the insulation for the top of the car applied'in accordance with this invention.

Figure 2v is a view iny transverse section taken on the line 2-2 of Figure l7 illustra-ting the roof in place.` i

Figure 3 is a View in transverse section taken on the line 3-3'of Figure l, illustrating the means for securing the insulation for the top of the car.

Figure a is a detail sectionalview taken on the line 4--4 of Figure 3.

Cars of this type are usually constructed with an inner sheathing of wood about the sides and top with layers of 'insulation ma-I terial between the sheathing and the sides and roof. In building the car, the sides and Vends are first erected upon'the car body the insulation material placed about the side7 the inner sheathing applied to the ysides and,top, the top insulation installed,

such a manner that when the main carlines ing and side plates and hold tle edges in ner, a sub carline 3 is laid onthe top sheath` ing under the position tof be occupiedby each main carline. An insulation supporting sheathing 5 is laid from end to end and from side to side upon the sub vcarlines and is` supported ythereby leaving an air` space between the sub carlines, top sheathing l and supporting sheathing 5. The insulation-material 6 in continuous sheets'of slightlyl greater width than the distance between the side plates is laid upon the supporting sheathing from hatch tol hatch and maybe made up of as many layers or of such material as desired.

While the main carlines i vare illustrated as being of a particular type any form of carline that is provided with a horizontal bottom portion may be employed. The main carlines are thenplaced in position and forced down upon the layer or layers of in sulation material over eachI sub carline. The insulation material is` compressible andthe sub carlines are constructed and secured in 'i vthe weaving action Vof the car while in motion. y The vinsulation .materialfis slightly wider than the width of the car and is secured by wooden cleats 7 nailed or otherwise secured 90 through the edges of the sheet to the side plates between the carlines 'on the upperl side of the sheet. These cleats compress the insulation between .the supporting sheath positionv while ythe central portion is held between the sub and main carlines.`

Asthere are usually two hatch openings at each end of the `car whose sides 8y are extended downward through the top sheathing l, it is necessary to apply sections of insulation about them or make apertures in the continuous sheets to accommodate the openings The insulation material is secured about the sides of the hatches and to `the end plates of the car by cleats in the lit is secured to the side same manner as plates.

`Nhat I claim is:

1. In a refrigerator car, side and end plates., a sheathing extending across the top of the car between the end and side plates,

subcal'linejs between the side plates above the elgeqthmg, Je eoutmuous sheet o *insula- *non materlal Supported upon the subemlnes, and main czulnes each having a hori-` zon'ul bottom porlon engaging the meule` tion material above the sub om'lnes, and

cleats between the main cal-lines securingy the eclgesol the Sheet to the side platee.

2. The method of afl inw nslaton io the top of a rel'gereor 0:11' comprising the eliectmg of the sldes and ends ofthe ozu, the

consrucon of he iop sheathing, the placmg of' sub-cellules theeoxfer, the applymg y oilf a Continuous sheet` of sulaton material the edges of the sheet to the side plates by 2o cleats.
